Abstract
A method of determining a recording power used to record information to an optical disc, includes carrying out test recording which records predetermined data to a predetermined area of the optical disc to determine the recording power, and recording predetermined data with a power equal to or more than the determined recording power to an area adjacent to the predetermined area.
Claims12
A method of determining a recording power used to record information to an optical disc, said method comprising:
- determining the recording power by test recording which records predetermined data to an area in a test recording area of the optical disc;
- and
- after the recording power is determined, continually recording predetermined data with a power equal to or more than the determined recording power to an unused area in the test recording area, the unused area being adjacent to the area in the test recording area, at which the test recording has been just carried out, to determine the recording power.
An apparatus for recording information to an optical disc, said apparatus comprising:
- a power determining section operable to determine a recording power by test recording which records predetermined data to an area in a test recording area of the optical disc;
- and
- a recording section operable to, after the recording power is determined by the power determining section, continually record predetermined data, with a power equal to or more than the determined recording power, to an unused area in the test recording area, the unused area being adjacent to the area in the test recording area, at which the test recording has been just carried out, to determine the recording power.
